To all whom it may conccm:

Be it known that I, IRA SnLrzniz, a citizen of the United States, residing at .Vaterbury, in the county or" New Haven and State of Connecticut, have invented a new and useful Improvement in incandescent-Lamp Sockets; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings con stitute part of this application, and represent in- Fig. 1 a view in side elevation of a lampsocket body embodying my invention.

Fig. 2 a plan view thereof.

My invention relates to an improved incandescent lamp-socket, the object being to produce a simple, compact and efiicient socket constructed with particular reference to protecting the wires from abrasion and injury.

With these ends in View, my invention consists in an incandescent lamp-socket having certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out my invention, as herein shown, I employ a socket-body t made of porcelain or any molded suitable insulating composition, and provided at the time of being molded with an internally threaded coupling-sleeve 5' having an embedded anchoring-fiange 6 and adapting the sockethody to be applied to the outlet pipe through which the wires are led. The socketrbody is also provided, at the time of being molded, with a centrally depending eyelet 7 and two depending eyelet-s 8 arranged on opposite sides thereof. The coupling-sleeve 5 opens directly at its innor end into an internal concentric passage 9 from which two smaller, corresponding passages 10 lead in opposite directions into deep lateral recesses 11 termed at opposite points in tee periphery of the body, the said passages 9 and 10 and the recesses ll being formed in the body at the time of molding the same to permit the wires 12 and 13 to be led directly through the iii-- terior of the body.

The central eyelet 7 is employed for the attachment of a terminal plate 14 and a spring contact-finger 15, as clearly shown in Fig. 7, the plate 14 carrying a bindingscrew 16. The lateral eyelets 8 are employed for the attachment to the body, as shown in 6 and 7, of a yoke-shaped terminalplate 17 and a screw-shell 18, the former being provided as usual with a binding-screw 19. After the parts have been assembled they enclosed by an insulating shell 20 fitting over the screw-shell l8 and abutting against a shoulder 21 molded in the body 4.

It will be seen by particular reference to Fig. 7 that the wires 12 and 13 instead of being led around on the outside of the body, arepassed directly through the coupling-sleeve 5 into the interior of the body where they are connected with the respective binding-screws of the terminal-plate at points so far within the periphery of the body that they are entirely protected against those abrasions which occur when the wires are led around on the outside of the ody and let into shallow peripheral notches therein as in the sockets of the prior art.

I claim:

1. in an incandescent lamp socket, the combination with a molded body formed with internally-arranged passages for the current-receiving wires, of an internallythreaded coupling-sleeve anchored in the said body when the same is molded, and having its inner end open to communicate with the passages thereof, terminal plates and a spring-contact applied to the body within the periphery thereof, and an insulating shell applied over the body, whereby the current-carrying wires are located within the periphery oi: the bod and their abrasion prevented.

2. in an incandescent lamp-socket, the combination with a molded body formed with a concentric main passage, two secilti ondary passages leading in opposite directions therefrom and two deep recesses formed in the periphery of the body and respectively communicating with the said secondary passages; of an internally-threaded coupling-sleeve anchored in the said body when the same is molded and open at its inner end to communicate with the concentric main passage thereof, terminal plates and a spring-contact located within the said body, and an insulating shell applied over the body.

lets, and an insulating shell applied over the said body and screw-shell 7 42.111 an incandescent lamp-socket, the

combination With a molded body made of insulating material and formed with internally-arranged passages, of an internallytln'eaded coupling-sleeve molded into the said body and having its inner end open to communicate with the said passages, central and lateral eyelets molded into the body, a terminal-plate and a spring-contact applied to tliecentral eyelet, a yoke-shaped terminal-plate and a threaded shell applied to the lateral eyelets, and an insulating shell applied over the said body.
